The following tutorials are based on my exploration of Frank Luna's Introduction to 3D Game Programming with Direct3D 11.0, adapting the C++ original code into C#, using SlimDX as a managed wrapper for the DirectX libraries.
The code for all of these examples can be found on my GitHub public repository.
To compile and run the examples, you will need Visual Studio 2012. I have the Professional edition, but I would imagine that you should be able to use the C# Express edition as well. You will also need SlimDX, which is also available through NuGet, as well as the DirectX SDK. If you are running Windows 8 or greater, DirectX is now included in the Windows SDK, so you will want to grab that for the most updated version of DirectX.
Some of the examples use Assimp.Net to load 3D models. You can download this from Google Code.
